How to check disk I/O performance in Windows OS and Linux? First of all, type top command in the terminal to check the load on your server.
If the output is not satisfactory, then look into wa status to know the status of Reading and Write IOPS on the hard disk..
The iozone is a great tool that measures disk performance from a broad range of aspects in the form of different file operations.
For example, with iozone, we can measure the performance of the disk on file operations like sequential read-write, random read-write, re-read and re-write, stridden read, and many more.Aug 16, 2023.
If it is high, then we need to check I/O activity in Linux box using the iotop or iostat commands.
By using iotop command, you can monitor the disk utilization by individual processes.
You will get the following output: By typing the iotop command with o option, you will get the actual I/O activity..
Using the vmstat command
The vmstat command is also known as virtual memory statistics.
It is a system performance monitoring utility in Linux that displays information about processes, memory, CPU scheduling, disk, and block IO.
It shows users the real-time system performance during a sampling period..
Input/Output (I/O) redirection in Linux refers to the ability of the Linux operating system that allows us to change the standard input ( stdin ) and standard output ( stdout ) when executing a command on the terminal.
By default, the standard input device is your keyboard and the standard output device is your screen..
